Anyone notice the tire pressure displayed on dash is wrong?
On my '19 Forester tire readings displayed on the dash for each tire is always about 4-6 PSI lower than the actual tire pressure. I have two digital tire pressure gauges that read the same pressure value so I believe that over the displayed pressure on the dash.

You remind me of someone who either can't read, don't believe what they read or you are a democrat.lol

Google this and you'd get 100 sources saying it's true and just as many saying it's untrue. So take your pick and have a nice day.

Costco doesn't always do it right.

Bought tires at Costco last year. TPMS light came on during my short drive home. Checked the tire pressure when I got home and all four tires were severely underinflated, around 18 to 22 PSI in each. Fortunately I have an air compressor and was able to refill the tires but had to use normal air that contains "only" 78% nitrogen (the horror) .
Lessoned learned. Check your tire pressure after all tire services (new tires, balance, rotation or whatever). Over the years I have had a couple of incidents where my tires were severely overinflated by 10+ psi (not at Costco).

And no, I don't buy in to the nitrogen inflated tires thing, especially for the typical passenger car tire as IMHO the benefits, if any, are extremely minute. But, that's another subject for another day.......

So, whatís wrong with asking for supporting evidence of a claim? Do you believe everything you read on the Internet?

And, while weíre at it... what does political sarcasm have to do with the subject?

No I don't believe everthing I read on the Internet but it's hard to give you supporting evidence with the use of the net. Like I said, look it up and make up your own mind.

Since I live in upstate SC, where Michelin has its NA headquarters, Im fortunate to know a few engineers that work for them in the tire manufacturing areas.

Iíve heard this argument about OEM tires being different than aftermarket tires for some years now, so Iíve gone to the source to find out what they say about it.

The consensus that Iíve gotten from asking them:

Auto manufacturers did indeed often have tires manufactured specifically to vehicle maker specifications. However, the same tire manufacturer make/model and sized tire, whether OEM or bought as replacements later, use the very same specifications. Thatís why you can read tire reviews (ie., Tirerack.com) for a specific make/model tire that, depending on specific size, can give wide mileage variations and service levels.

So, for example, even though the tread pattern is the same, a 185/65R15 size in a particular make/model tire might give very different ride and wear results than the same tire in a 205/60R16.

I donít have any engineering document copies to prove/disprove this, but it makes sense (at least to me).

OEM tire size equates to the Manufacturer's replacement. Then it is the same tire with the same specifications which as stated no difference for set vehicle.

If that wasnít the case, and OEM same-model/manufacturer/sized tires were different that the tires being sold by tire dealers... can you imagine the field day lawyers would have suing tire manufacturers, claiming no consumer could possibly ever know what the actual product was being purchased?

Yup, it works. I often go for the chicken and I still walk out with 10 items in teh basket and it costs $100. Damn it!

Hotdogs must be a loss leader too. I dont know how they can sell a dog and giant coke for a buck fifty.

Cheers,
Scott
